The domain coinku[.]io was registered on June 29, 2025 through GoDaddy.com, LLC. DNS resolution points to 104.21.20.86, an IP address owned by Cloudflare (AS13335) and geolocated in the United States. Authoritative name servers are david.ns.cloudflare.com and susan.ns.cloudflare.com. HTTP requests return a 521 “Web server is down” status and the page title is “coinku[.]io | 521: Web server is down”. VirusTotal records indicate two of 91 scanners flag the domain. The domain appears on three security blocklists and is blocked by PhishDestroy, MetaMask, and SEAL. The SSL certificate is issued by Google Trust Services / WE1. Intelligence categorizes the activity as a crypto drainer, a variant of generic phishing that seeks to steal cryptocurrency assets. Gridinsoft assigns a trust score of 78/100. No additional page content has been captured; the current response provides no visible malicious payload, leaving the precise lure uncertain. Analysts should continue monitoring the domain for changes in HTTP response, new infrastructure, or victim reports. Defensive measures include adding coinku[.]io to URL filtering, blocking the IP 104.21.20.86, and applying TLS inspection where feasible. Given the high‑risk rating and active status, any communication originating from coinku[.]io should be treated as malicious, especially for organizations handling cryptocurrency transactions.

Beware of recovery scammers! After being scammed, criminals may contact you again pretending to be "recovery agents," lawyers, or investigators who claim they can retrieve your lost funds — for a fee. This is a second scam. No legitimate service will ask for upfront payment to recover stolen crypto. Learn more about recovery fraud →

Recommendations & Advice for Victims
An estimated $51 billion flowed to illicit crypto wallets in 2024 (source). If you interacted with coinku.io — act now.
What should I do immediately?
Urgent
- Revoke token approvals — use revoke.cash to remove access granted to malicious smart contracts
- Move remaining funds to a brand-new wallet. The compromised wallet is no longer safe
- Change all passwords — email, exchange accounts, anything that shares the same password
- Enable 2FA using an authenticator app (not SMS). Disable SMS-based recovery
- Freeze cards if you entered banking details on the phishing site
What information should I collect for my report?
FBI guidelines
According to the FBI, the most important details are transaction data:
- Cryptocurrency addresses — scammer's wallet (e.g.,
0x5856...35985) - Amount & crypto type — exact amount (e.g., 1.02345 ETH, 0.5 BTC, 500 USDT)
- Transaction ID (hash) — the unique blockchain transaction identifier
- Exact dates & times — of each transaction and first contact with scammer
- Screenshots — scam website, chat messages, emails, wallet transactions, social media
- All URLs & domains used by the scammer (including
coinku.io) - Communications — emails, texts, phone numbers, usernames the scammer used
Even if you don't have all details — file a report anyway. Partial information still helps investigations.
Where should I report the scam?
- FBI IC3 — Internet Crime Complaint Center (US federal reporting)
- Europol — European cybercrime reporting (EU)
- Chainabuse — flag scam wallets across exchanges & platforms
- Your crypto exchange — contact Coinbase/Binance/Kraken support to freeze scammer's address
- Local police — creates an official record, even if they can't act immediately
The FBI recovered over $1 billion in crypto fraud in 2024 thanks to victim reports. Your report matters.
How do crypto scams typically work?
- Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
- Malicious approvals — "connect wallet" prompts that grant unlimited token spending to attackers
- Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
- Recovery scams — victims targeted AGAIN by fake "recovery agents" demanding upfront fees. Always a scam
- Fake ads & airdrops — Google/social media ads and "free token" offers leading to wallet drainers
- AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect
How can I protect myself in the future?
- Use a hardware wallet (Ledger, Trezor). Never store large amounts in browser wallets
- Bookmark official sites — never click links from emails, DMs, or ads
- Read every approval — verify permissions before signing. Reject unlimited approvals
- Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
- "Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines
How big is the crypto scam problem?
- $51 billion flowed to illicit crypto wallets in 2024 — CoinLedger
- Pig butchering losses grew 40% year over year, now the fastest-growing fraud type
- Only ~5% of victims report — your report helps shut down criminal networks
- FBI recovered $1B+ in 2024 thanks to victim reports — FBI.gov
